Jason Lane‘s improbable comeback story will add another chapter today when the outfielder-turned-pitcher will receive his first Major League start, getting a spot appearance in place of Padres ace Ian Kennedy (who’s battling a sore oblique). Lane began making regular mound appearances in 2012 in the minors in an attempt to revive his career, and the decision paid off earlier this season when he was called up by San Diego and threw 4 1/3 scoreless relief innings. That cup of coffee marked Lane’s first big league action since playing as an outfielder with the Astros and Padres from 2002-07. At age 37, Lane will be the oldest first-time starter since 38-year-old Troy Percival started a game for St. Louis in 2007.

Here’s some hot stove buzz from around the NL West…

Despite already trading two of their better prospects in the Jake Peavydeal, the Giants have maintained an interest in Ben Zobrist and had two scouts watching the Rays this weekend, FOX Sports’ Jon Paul Morosi reports (Twitterlinks). San Francisco is one of “multiple teams” who are “ready to act” if Tampa indeed makes Zobrist available, sources tell Morosi and Ken Rosenthal.

Multiple teams have shown interest in Diamondbacks right-hander Brad Ziegler, MLB.com’s Steve Gilbert reports, though the Snakes aren’t likely to move him. Earlier this month, we heard the Tigers were known to be one of the clubs who asked about Ziegler. Gilbert’s piece also summarizes some of the trade rumors circulating about what Arizona may do at the deadline.

Troy Tulowitzki would welcome a trade to the Red Sox, Peter Abraham of the Boston Globe hears from a source (Twitter link). Given Tulowitzki’s controversial appearance in the stands at Sunday’s Blue Jays/Yankees game, expect more trade buzz than ever about the Rockies‘ star shortstop both over the next several weeks and through the offseason.

Dodgers GM Ned Colletti said over the weekend that his club “may not do anything” at the trade deadline, and Mark Saxon of ESPN Los Angeles thinks this might not necessarily be a concern given how the current roster performed in sweeping the Giants.
